The remainder of Intel's Skylake lineup has been fully detailed. To this point, only the i5-6600K ($240) and i7-6700K (which we reviewed) have been announced, with the non-K SKU and Core i3 CPUs lacking details. Below is a table of specs for Intel's new i3-6100, i3-6300, i5-6600, i5-6500, i7-6700, and other Skylake CPUs.

The major items for discussion include the i5-6600 vs. i5-6600K & i5-4670/4690, the i3-6100 vs. the i3-4130, and i7-6700 vs. i7-6700K & 4770/4790.

Starting with the specs:

Recapping the primary advancements in bullet form:

  • The i3-6300 decreases TDP 7W (47W vs. 54W) over the i3-4300 series, while increasing the clockrate by 300MHz (3.8GHz from 3.5GHz). Price is expected to be about identical, at $147 wholesale for a box of 1000.
  • The i3-6100 decreases TDP 7W (47W vs. 54W) over the i3-4130, while increasing the clockrate by 300MHz (3.7GHz from 3.4GHz). The i3-4160 refreshed CPU sees only a 100MHz clockrate gain. Price is around the same as the Haswell 4100 series, at $117 wholesale for 1000.
  • The i5-6600 decreases TDP 19W (65W vs. 84W) over the i5-4670/4690, while increasing clockrate by 100MHz over the 4670. The price is $202 for a box of 1000.
  • The i5-6600 vs. i5-6600K sees a slight 0.2GHz clockrate decrease (200MHz) and loses OC support, but is expected to be priced ~$20 cheaper. This mirrors Haswell and Ivy Bridge non-K pricing.
  • The i7-6700 decreases TDP 19W (65W vs. 84W) over the i7-4770, while maintaining about the same clockrate (3.4GHz and 3.9GHz Turbo on the Haswell chip, 3.4GHz and 4.0GHz Turbo on Skylake). Price is $312 for 1000.
  • The i7-6700 vs. i7-6700K price disparity is expected around $40 cheaper, with a measurable 600MHz (0.6GHz) clockrate decrease on the 6700 non-K CPU.

Intel also announced its Core M and T-SKU CPUs for mobile and power restrictive configurations. We have not yet looked into mobile Skylake chips, but hope to review some in the future.

The prices and product stack mirror previous generation Intel CPUs pretty closely, with purchasing choices hinging upon whether or not users want to overclock their CPU. The K-SKU CPUs are binned-out to a higher class, granted, but users prioritizing build cost over OC support and bins should consider the new non-K CPUs.

The upstart cost for Skylake, as we've already discussed, is higher given the requirement of DDR4 and a Z170 platform; for this reason, Broadwell and Devil's Canyon (Haswell's 4790, 4690 CPUs) are still worth consideration.

Steve started GamersNexus back when it was just a cool name, and now it's grown into an expansive website with an overwhelming amount of features. He recalls his first difficult decision with GN's direction: "I didn't know whether or not I wanted 'Gamers' to have a possessive apostrophe -- I mean, grammatically it should, but I didn't like it in the name. It was ugly. I also had people who were typing apostrophes into the address bar - sigh. It made sense to just leave it as 'Gamers.'"

First world problems, Steve. First world problems.
